The curing of positive plates for lead–acid batteries is a critical operation. During this process, the chemical and physical structure of the active-material is established and the plates develop the strength that is required for subsequent mechanical handling. (1. Introduction)
To rejuvenate a lead acid battery, add extra acid if part of the battery's acid has spilled out. This will help the battery maintain the correct quantity of water and potentially allow it to operate again. However, only add acid to the battery if part of the acid has spilled out.
This page will guide you through process of restoring an old, sulfated lead acid battery to like new conditions with almost no investment. The only required materials are a dead battery, distilled water and a homemade battery rejuvenator. This process should restore any lead acid type battery that is sulfated due to old age or use.
During curing, the plates of lead/acid batteries undergo a chemical process, involving free lead and oxygen, which is known as the hydroset process. The chemical combination is an exothermic type reaction that requires a water catalyst Studies have shown that the rate of reaction is dependent on the amount of water present in the plates.
During curing the following processes take place: Pb oxidation; recrystallization of 3BS, 4BS and PbO; grid corrosion; improvement of the paste/grid contact, and drying of the paste. With increase of curing temperature the rates of the curing processes will be accelerated and curing time can be shortened.
Batteries with plates produced with 4BS and then cured at 90 o C for less than 4 h have both satisfactory power output and cycle life. Curing of negative plates. For high tech battery manufacture the duration of curing of negative plates should be less than 8 hours.
